On the other hand, the concentration of this kind of air pollution is higher the closer it is to the ground, and the children's height is lower, which obviously causes more harm
At present, there are no effective measures to deal with it

Embodiment 1
[0033] A construction method for a non-toxic and environmentally friendly plastic floor for a kindergarten, comprising the following steps:
[0034] S1, pavement of base layer 1: pave base layer 1 and level it;
[0035] S2, pavement of the waterproof adhesive layer 2: brush the waterproof adhesive on the base layer 1 obtained in S1, and the waterproof adhesive penetrates into the base layer and solidifies to form a waterproof adhesive layer 2;
[0036] S3, laying the bottom layer 3: paving the bottom layer 3 on the waterproof adhesive layer 4 and leveling it;
[0037] S4, pavement of the second adhesive layer 4: after the curing of the underlying material laid in S3 is completed, spray the second adhesive layer 4;
[0038] S5, pavement of surface layer 5: choose EPDM particles of different colors according to needs, the diameter of the EPDM particles is 1-3mm, mix with MDI glue and crush, and then pave on the second bonding layer 4 .
[0039] The present invention is far sup...

Abstract
The invention provides a nontoxic environment-friendly plastic ground for a kindergarten and a construction method. The nontoxic environment-friendly plastic ground comprises a base layer. A waterproof bonding layer is arranged on the base layer and partially permeates into the base layer. The waterproof bonding layer is sequentially provided with a bottom layer, a second bonding layer and a surface layer from bottom to top. The nontoxic environment-friendly plastic ground for the kindergarten has the advantages that only MID glue is used for bonding, and thus the bonding effect is good; due to the fact that the viscidity of the glue before solidification is small, construction is easier and more convenient compared with TDI, and smearing is easier and more uniform; the compatibility of the MDI glue contained in different layers can be guaranteed, and thus delamination is unlikely to occur; compared with a TDI glue system, the harm of the MDI glue to the human body is extremely small, so that pollution is avoided in the use process, and the softness and safety are good; the surface layer has ultraviolet ray blocking and toxic gas sealing functions to a certain extent, and thus the color of EPDM is unlikely to change in the use process, and pollution is smaller; and since the MDI glue content of each layer is high, compared with an ordinary plastic ground with the same thickness, the nontoxic environment-friendly plastic ground is good in elasticity and long in service life.
Description
Technical field: [0001] The invention relates to a non-toxic and environment-friendly plastic floor for kindergartens and a construction method. Background technique: [0002] At present, the plastic floors or runways laid in domestic kindergartens mostly use semi-prepolymers formed by the reaction of toluene diisocyanate (TDI) and polyether polyols as binders. TDI is a water-white or light yellow liquid with a strong pungent odor, which is accumulative and latent in the human body, and has a strong irritating effect on the skin, eyes and respiratory tract. Inhalation of high-concentration TDI vapor can cause bronchitis and bronchopneumonia and pulmonary edema; contact of fluid with skin may cause dermatitis. Liquid contact with eyes can cause severe irritation which, if left untreated, may result in permanent damage. Long-term exposure to TDI can cause chronic bronchitis. Those who are allergic to TDI may cause wheezing, wheezing, dyspnea and coughing. When TDI is hot o...
